Airavata is the elephant carrier of Lord Indra. Airavata came and put water from the Ganges here, with which he bathed Lord Krishna. This kunda is close to Surabhi Kunda.
This kunda is on your left hand side, if you continue on the inside parikrama path another 250m past Surabhi Kunda. It is a good-sized kunda with a three foot wall around it.
